Nut consumption inversely associated with risk on AF and HF

Nut consumption and incidence of seven cardiovascular diseases

Literature - Larsson SC, Drca N, Bjorck M, et al. - Heart 2018;0:1–6

Introduction and methods

Meta-analyses of prospective studies have shown an inversed association between nut consumption and CV death, coronary heart disease and stroke [1]. However, the relation between nut consumption and incidence of seven specific CVD remains unknown.

This prospective study included 61,364 participants (aged 45-83 years) of the Cohort of Swedish Men and the Swedish Mammography Cohort who filled out the Food Frequency Questionnaire about their average nut consumption. The relation between nut consumption and the incidence of seven CVD was studied by combining this questionnaire with the Swedish National Patient and Death Registers.

Participants missing a personal identity number as well as those with prevalent CVD, cancer, an extreme energy intake and those who left the questionnaire unanswered were excluded.

The relation between nut consumption and seven CVD was investigated by analyzing data obtained between January 1998 and December 2014. The aim was to examine a linear association between average nut consumption and incidence of acute myocardial infarction, heart failure (HF), atrial fibrillation (AF), aortic valve stenosis, abdominal aortic aneurysm, ischemic stroke and intracerebral hemorrhage.

Main results

Conclusion

This prospective study showed an inversed association between nut consumption and the risk on AF HF. Therefore, nut consumption might reduce the risk on these CVD events.
